CUSHION CAP FOR STAPLING MACHINES AND THE LIKE.

Application filed December 10, 1824. Serial No. 754,960.

To all whom it may concern:

Be it known that I, ROMAN H. H EYN, a citizen of the United States, residlngJ at Westport, county of Fairfield, State of o necticut, have. invented a new and useful Cushion Cap for Stapling Machines and the like, of which the following is'a speclfication.

This invention relates to a cusion cap for stapling machines and similar devices in which there is a head or similar element operated by a blow of the hand to operate the device, and has for an object to provide an 1mproved auxiliary cap for the operating head made of relatively soft flexible and yielding material such as rubber, which may be readily attached to the head and will protect the hand against injury in operating the device.

With the foregoing and other ob ects in view, I have devised the construction illus trated in the accompanying drawing fOIID- ing a part of this specification, similar reference characters being employed throughout. the various figures to indicate corresponding elements. In this drawing,

Fig. 1 is a side elevation of a stapling machine showing my improved cushion cap 111 position.

Fig. 2 is a transverse section through the operating head of the machine and the cap as applied thereto.

Fig. 3 is a bottom plan view of the cap removed from the head, and

Fig. is a transverse section of the same substantially on line 44 of Fig. 3.

By way of illustration I have shown my improved cushion cap as applied to the operating head of a stapling machine, but it is to be understood it is not confined to use therewith but is equally adapted for use on similarly operated devices, such as dating machines and the like. The stapling machine illustrated comprises the usual base 10 having a housing 11 pivoted thereto at 12,

and which housing carries the stapling mechanism, including the vertically reciprocable plun er 13 operated in the usual manner by a b ow on the head 14 secured to the upper end of this plunger, the plunger being normally held in elevated position by a spring 15. These devices are usually operated by a blow of the hand on the top of the head, and if the device is used a great deal, or if the staple cutting devices are somewhat blow of the hand but will immediately spring back to the original position when pressure is relieved. This cap comprises a dome shaped body portion 16 provided on its inner surface with a number of inwardly projecting, yieldable supporting elements. such as lugs 17 preferably formed integral with the body member and of the same soft,

yieldable resilient material. he lower ends of these lugs are arranged to engage the top surface of the head 14 and support the body 16 of the cap spaced from the top of the head as shown in Fig. 2,- so that when the cap is struck a blow in operating the machine these lugs will yield and give a cushioning eifect relieving the injurious effect of the blow on the hand. The lugs are preferably of greater length at the center of the cap than adjacent the side edges thereof as shown, as the greatest movement and cush ioning efl'ect is desired at the center of the cap.

The cap is preferably secured to the head by means ofa downwardly and inwardly curved flange 18, which is adapted to extend around under and embrace the lower edge of the flange 19 of the head 14, and as this flange is of a flexible resilient material it will grip the flange of the head securely holding the cap in position. It may, however, be easil applied and removed at any time desire The cap is preferably molded in one piece of plastic rubber and then vulcanized to give the proper resiliency.

Having thus set forth the nature of my invention, what I claim is:

1. A cushion cap for stapling machines and the like comprising an integral one iece dome shaped member of flexible resi 'ent material having spaced, solid, flexible cushioning lugs projecting inwardly from the inner surface thereof, said lugs being of such dimensions as to support the cap under a blow and to return the cap to normal position immediately after the pressure is re- H and the like-comprising an integral one piece dome shaped member of fle cible resilient material having spaced, sohd, flexible cushinwardly from the ioning lugs pro{1ectin inner surface t ereo and gradually de- 4 creasing in height from the center toward such dimensions as to support the cap under a blow and to return the cap to normal posltion immediately after the pressure is relieved, and an inwardly extending flexible 15 rubber securing flange on the under side of said cap for securing it to the olpieirating head of a staplin machine and the e.

In testimony w ereof I afiix my signature.
